Oman STP project draws global bids

September 2015

Oman’s proposed new sewage treatment plant (STP) project, estimated to cost about $100 million, has attracted tenders from three global firms.

The plant in Misfah in the Wilayat of Bausher will cater to sewage transported by bowser trucks long after much of Muscat has been connected to a world-class sewerage collection system.

Bids have been received from Spanish-based global integrated water technology specialist Abeima, which submitted the lowest bid, Suez Environment, CCC and India-based multinational VA Tech Wabag.

The successful bidder will secure a contract to design, build and operate the tanker STP at Misfah, which is expected to start operations by the end of 2018.

Haya Water (Oman Wastewater Services Company), a wholly government-owned entity, is building a state-of-the-art sewerage collection and treatment system covering much of Muscat Governorate at a cost of around RO2 billion ($5 billion).

According to plans drawn by Haya Water, the STP will have a capacity of 32,000 cu m per day with an expansive tanker queuing area to accommodate up to 74 tankers at a time.

The facility will also come with 48 tanker discharge bays equipped with flow meters and online quality monitors.

At the downstream end of the facility, a pipeline will be installed to carry treated effluent to Haya Water’s storage tanks at Al Ansab, located some 14 km away.
